2.3 Shim adjustment at sides
of the boom bottom
(section [2] indicated in Figure 1)
1. Measure the inner dimension of the outer boom
box at the sliding position of the slide plates at
approximately 1.5 m (4.92 ft) from the boom
bottom.
2. Then, divide the dimension evenly between right
and left sides, and insert shims so that the gaps
become the minimum clearance.
[NOTICE]
If the boom cannot be inserted, measure the inner
dimension of the outer boom box at the boom
bottom.
3. Apply a thread locking agent (ThreeBond 1401 or
the equivalent) to the fixing bolt. Lightly tighten it
and then untighten it for 1/4 turns.
